Question

ifa=2+√5/2-√5 and b=2-√5/2+√5,then find the value of asquare -b square​

Answer 1

Answer:

0

Step-by-step explanation:

$a^{2} - b^{2}$ = (a+b)(a-b) (Just an identity bro:)

a = 2+√5/2-√5

b = 2-√5/2+√5

(a+b)(a-b)

= {(2+√5/2-√5) + (2-√5/2+√5)}{(2+√5/2-√5) - (2-√5/2+√5)}

= (4)(0)

= 0

Just some easy calculations bro!

Hope you understood:)
